摘要:
The invention relates to a formulation comprising a terpolymer and active substance (D), characterized in that said terpolymer comprises main chain segment (A), hydrophobic pendent chains (B), and hydrophilic pendent chains (C). The invention also relates to processes for the preparation of the formulation and a ready-for-use formulation comprising the inventive formulation.

摘要:
A formulation comprising a terpolymer and an active substance and the producing process thereof are disclosed. Said terpolymer comprises 17-60 wt.% of the main chain segment, 20-56 wt.% of the hydrophobic pendent chains, and 20-40 wt.% hydrophilic pendent chains, based on the total weight of the terpolymer. The main chain segment is formed from the monomer which is selected from (meth)acrylic acid, vinyl benzene sulfonic acid or N-isopropyl acrylamide. The hydrophobic pendent chain is derived from hydrophobic vinyl, such as alkyl (meth)acrylate, styrene and/or vinyl acetate. The hydrophilic pendent chain is derived from monomer which is selected from (polyethylene glycol monomethylether) acrylate, acrylamide, vinylpyrrolidone, or N,N-dimethylacrylamide.
